  53. 53. Case Study –Energy –Centre CDP Capital, Montreal Centre CDP Capital has numerous high performance features: • Operable windows • Double walled skin reduce excess heat gain, • High efficiency lighting, • High efficiency HVAC including VSD and energy recovery ventilation • Low NOx emitting boilers
  54. 54. Case Study –Energy – Steeles Technology Campus, Toronto “High Power Density tenants” – for example 24 hour computer rooms, and call centres. •An energy audit/evaluation included the lighting system, the heating plant, the cooling plant, the domestic hot water system, the HVAC distribution system and major equipment, and from this, •An energy management (reduction) plan •Monitoring of major energy uses. •Majority of the tenants being sub- metered. Analysis and reduction of peak energy demand. •Well-developed regular maintenance schedule of mechanical systems and building envelope
  55. 55. Case Study –Resources (Waste) – BCE Place, Toronto Following extensive waste audits in 2005, Brookfield introduced Project Blue – Make Recycling Second Nature, a program to promote recycling of paper, bottles, cans and coffee grounds. The target was to divert 75% of recyclable materials to appropriate bins rather than the garbage. 89% diversion rate achieved. Spot audits continue of various tenants. The Property Manager provides: •a recycling container for each workstation. •a large recycling container at all photocopiers. •a large recycling container in all kitchen areas for bottles and cans. •a small recycling container for coffee grounds and organics in the kitchens.
  56. 56. Case Study –Emissions (Hazmat) - Petro Canada Calgary •There are up-to-date MSDSs, spill clean- up kits and safety equipment kept near chemical storage areas. •The MSDSs are less than 3 years old. •WHMIS labels are present on regulated products. •Chemicals and hazardous materials are securely stored in externally ventilated spaces, under controlled temperature, with proper drainage protection, •There is a training program for staff •There are inventory and records of the hazardous waste. •There is a Health and Safety Committee •The pesticide contractor is licensed and employs integrated pest management methods.
  57. 57. Case Study –Indoor Environment–Royal Bank Winnipeg Capital items: •Being an older building, the building management wanted to be absolutely sure that the tenants were comfortable. •To make sure tenants are happy –that’s why fans were being kept running 24/7. •Air quality sensors were placed in tenant areas to measure CO2 levels. This showed that the building had been oversupplying and conditioning fresh air – not only when fully occupied, but even on weekends. •Monitoring the CO2 levels, made it possible to schedule fans to day/night cycle to ensure minimum settings while maintaining low CO2 levels. Combined savings with other energy measures - $54,000 or 20%.
  58. 58. Case Study –Indoor Environment –Stony Road NATURAL LIGHTING •The atrium provides the focal point of the building. •Natural light radiates into the atrium through the perimeter glazing, the glazed ceiling as well as the two 70 foot high massive glass walls at either end of the atrium. •To allow unblocked access of this natural light, there are very few enclosed offices on the perimeter of the building. •All windows have transparent blinds Built in 1996. that reduce glare while allowing a Received the BOMA Toronto “Certificate of view of the outside. Excellence” in both 2002 and 2005 and the “Office Building of the Year” and “TOBY” award in the Government Category Category in 2005
  59. 59. Case Study –Management –BCE Place, Toronto BCE Place has an excellent web-based tenant communications program that allows it to really move forward in changing lifestyle habits. For example, it engaged tenants in the City of Toronto Green Fleet Program, which includes workshops, activities and events that demonstrate that cycling is a viable, even enjoyable, transportation alternative for commuters in the GTA. The Green Fleet Program includes: • Workshop #1 - How Cycling Makes a Difference • Workshop #2 - Getting Started: The First Steps in Commuting by Bike • Workshop #3 - Tool Time: The Basics on Tuning Up Your Bike • Workshop #4 - Safe Cycling on the Streets
